      <h2>Description</h2>
      <p>
         MMI 1.3 is an XML Schema implementation derived from ISO ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 6.5.6.  
         It includes elements describing resource and metadata maintenance. 
         The XML schema was encoded using the rules described in ISO/TS 19139:2007.
